Thanks Mrs Lyell for barnacle specimens.

Mentions Agassiz’s classification of saurians.

Discusses letter from Chambers on "roads" in Scottish glens; views of Agassiz and Buckland on the glens.

Is reading Hugh Miller [First impressions of England and its people (1847)].

Mystified by the origin of coal-plants.

Milne’s Glen Roy theory is absurd but, oddly, it has staggered CD in favour of Agassiz’s ice-lake theory.

Supposition that glaciers made Glen Roy is a dream. Has received three letters from CD on river terraces. Reports on trip to terraces at Belleville. Comparison with Glen Roy.

Flattered by JBJ’s discussion of coral reefs [in Voyage of H.M.S. "Fly" 1 (1847): 347–8]. CD has always thought his Coral reefs "too bold and speculative", so he is gratified "when anyone who has had opportunities of observation does not give his verdict against it".

Discusses enclosed figures on elevation of terraces in several Scottish glens as surveyed by William Kemp and David Stevenson. Comments on Robert Chambers’ view of the terraces. Mentions a letter on the terraces, originally written for publication, which he has asked Robert Jameson [editor of the Edinburgh New Philos. J.] to destroy.

Difficulty of scheduling visit before JDH departs on Himalayan expedition.

Thanks for a suite of male and female specimens of Lepidoptera. Lack of difference in size of wings surprises CD; the female’s being smaller than male’s in early growth is new to him. Will ask a friend in India for comparable facts.

On scheduling farewell meeting.

Continued problems in scheduling farewell meeting.

CD very ill; tries to arrange departure meeting with JDH.

CD’s guess at composition of Maldive flora.

Has had two bad days with boils.

Is reading Last days of Pompeii [Edward Bulwer Lytton (1834)].

Accepts AC’s offer to conduct hybridisation experiments, and offers suggestions.

Sends book [Journal of researches, 2d ed. (1845)].

Reorders six 2–oz bottles with corks.

Has discovered another new planet [Flora]. Gives readings.

Thanks for the neat name and symbol he has given to the new planet; thinks H. C. Schumacher has read Hora for Flora. The next one will have to be called Thetis as so many have suggested that name.

Sends his first approximation of the elements of the asteroid Flora.

Thanks for his visit to Collingwood. Regarding JH's great work. Would like to exhibit them to the King of France.

Thought his letter had miscarried. Thanks for the gift of his recently published work [Cape Results]. Will be glad to supply any information from his own work on comets, which he hopes to send in the course of a few days. Is studying U. J. J. Leverrier's method of development by elimination.

One of GN's relatives, Henry Bunbury, is writing a book on the Cape and would like information on the educational system. Has advised Bunbury to write to JH. Would like a copy of the speech JH made at Cambridge in which he praised GN's government at the Cape. Comments on the present sorry state at the Cape.

Thanks for information [on latest platina research]. Has encountered 'a totally new metallic chemistry.' Searching for papers by Mr. Gros and Mr. Beiset. Describes JH's experiments with 'Platinoids,' which JH named like asteroids: Heberum, Astraeum, and Neptunium.
